How do I make sure Simulink Constants are coded as #define?

If I have a constant in the Simulink model, this ends up being defined in a structure which then ends up in RAM.
This results in really inefficient software as data needs to be loaded from ROM to RAM at startup and the compiled code has to load the same data from RAM. As the data is constant this also blocks the compiler from producong the most efficient code.
These constants should either be directly coded in the C code or #define
I can't find any settings that make this do what I need.

First off, glad the answer helped! Secondly -- yes, this page wasn't too straightforward to find.
I went into the MATLAB help and searched for "#define preprocessor". Then, I filtered my results to only look at Embedded Coder. Filtering by product generally helps remove the "noise" from my searches.
